Effect of the microstructure of EB-PVD thermal barrier coatings on the thermal conductivity and the methods to reduce the thermal conductivity
Thermal barrier coatings (TBCs) Electron beam-physical vapour deposition (EB-PVD) Thermal conductivity Zirconia
2009/11/1
Thermal Barrier Coatings (TBCs) were first successfully tested in the turbine section of a research gas turbine engine in the mid-1970s. By the early 1980s they had entered revenue service on the vane...
OPTIMAL PARAMETERIZATION IN THE MEASUREMENTS OF THE THERMAL DIFFUSIVITY OF THERMAL BARRIER COATINGS
laser flash method optimal parameterization parameter estimation

The paper presents an estimation procedure for the measurement of the thermal diffusivity of thermal barrier coatings deposited on thermal conductive substrates using the laser flash method when the t...
Analytical Modeling of Unsteady Aluminum Depletion in Thermal Barrier Coatings
thermal oxidation thermal barrier coating aluminum depletion alumina di usion coecient
2009/10/13
The oxidation behavior of thermal barrier coatings (TBCs) in aircraft turbines is studied. A simple,unsteady and one-dimensional, di usion model based on aluminum depletion from a bond-coat to form an...
In the case of electrically conducting layers prepared on a glass substrate, sodium diffuses into the SnO2 film and deteriorates their electric properties. Sodium barrier diffusion properties of thin ...
